PROBLEM TO BE SOLVED: To provide a segment which can avoid localized concentric application of stress thereof to concrete, and can stably maintain the quality thereof. SOLUTION: The segment is formed such that a female portion (female fitting) 33<SB>2</SB>thereof having an open hollow portion, is embedded in a connection end face 31<SB>1</SB>of the segment 2a<SB>2</SB>, and that a male portion (male fitting) 32 firmly protruded from a connection end face 31<SB>2</SB>of the other segment 2a<SB>1</SB>is press-fitted into the open hollow portion, whereby both the segments are connected together. According to the structure of the segment, the female fitting has an integrally formed anchor support portion 33b which is arranged on one side of the female fitting opposite to the opening, and the anchor support portion has an anchor member 33e attached thereto so as to protrude on a side opposite to the opening. Then the anchor support portion and the anchor member are embedded in a segment main body 35 to settle the female fitting. COPYRIGHT: (C)2006,JPO&NCIPI
